BURNER FOR OIL-LAMPS.

SPECIFICATION forming part of Letters Patent No. 623,443, dated April18,1899.

' Application filed January 19,1898. Serial No. 667,180. (No model.)

To all whom it may concern:

Be it known that I, CECIL THROOKMORTON, gentleman, a subject of theQueen of Great Britain, residing at Greylands, Glennies Creek, nearSingleton, in the British Colony of New South VJales, have invented anew and useful Improved Burner for Oil-Lamps,

of which the following is a specification.

This invention relates to an improved burner for oil-lamps, which thoughspecially devised for lamps such as those for domestic purposes in whichkerosene, paraflin, or like high-grade oil is used is yet applicable toall lamps in which hydrocarbon oils more or less easily vaporized areused.

This improved burner for oil-lamps consists of two main partsa tip and avaporizingcell, the former forming the top of the latter, the bottom ofwhich latter is in connection with an oil'reservoir. The tip is made ofrefractory heat-conducting material of more or less porous nature, suchas plaster-of-paris or such as fire-clay or the like, mixed withcombustible material, but out of which the said combustible material hasbeen burned. This tip is perforated and is firmly fixed to the top ofthe vaporizing-cell, which vaporizing-cell is filled or nearly filledwith fibrous or spongy materialsuch as tow, cotton-waste, or the likeorwith other material which will split up or divide the oil.

In one construction of this improved burner, which is used when theoil-reservoir is above the level of the burner, the bottom of thevaporizing-cell is connected to said reservoir by a bent pipe having aregulating-tap or other device, such as a bird-fountain connection orother means, for regulating the amount of oil supplied through the bentpipe to the burner.

In a modified construction of this burner, which is used when theoil-reservoir is below the burner, as in ordinary hand or table lamps,the vaporizing-cell is affixed to the top of the wick-tube, and theordinary wick terminates in the fibrous or spongy filling in said cell.

In order to the saving of the oil, to the prevention of the charring orburning of the filling material of the cell, and to the speedyextinguishment of the lamp, a movable head is combined with the burner,adapted to stand clear of the tip and to closely fit over the tip whenrequired to cut off the supply of oxygen thereto; but in order that thisinvention may be clearly understood reference will now be made to thedrawings herewith, in which Figures 1 and 2 are cross-sectionalelevations at right angles, respectively, of one construction of thisimproved burner for oillamps specially devised for use on a lamp havingthe oil-reservoir above the level of the burner, and these views showthe extinguishing cap or hood in position closed over the tip. Figs. 3and 4 are a central sectional elevation and a plan, respectively, of amodified construction of burner for use on an ordinary hand or-tablelamp or a lamp having its oilreservoir below its burner, and in theseviews the extinguishing cap or hood is shown as elevated clear of thetip, and in Fig. 4c the burnercone is removed. Fig. 5 is an enlargedcrosssectional elevation of the burner; Fig. 6, a plan of the tip, andFig. 7 a longitudinal ele vation of the burner. p

A is the tip; B, the vaporizing chamber or cell; 0, the oil-supply pipeor wick-tube; D, an ordinary slotted burner-cone, and E an ordinarychimney gallery or support. The tip A, of refractory and porousmaterial, has perforations A as shown, medially of itslength, and it hasgrooves A into which spring the upper edges 13 of the vaporizing-cell B,thus firmly holding it in position. The lower parts A of this tip extenddownwardly, as shown, into the filling B of the vaporizing-chamber, saidfilling being of a fibrous or spongy nature, such as the materialsbefore mentioned, or asbestos or any other material which will split upor divide the oil which enters the Vaporizing-cell. In the burners shownin Figs. 1 and 2 this vaporizing-cell Bis connected with branch pipes Cto the main supply-pipe O,which has'a tap or valve C or othercontrivance for regulating the supply of oil to said vaporizing-cell. Inthe construction of burner shown in Figs. 3 and 4 this vaporizing-cell Bhas an inset channel or socket B adapted to tightlyfit over the top ofthe wick-tube,which wick-tube contains an ordinary wick O as shown,dipping into the oil-reservoir. On the side of the vaporizing-cell Bishinged at F contained therein burns and so heatssu'ch tip and itsdownward extensions A causingthe oil in chamber or cell B to vaporize,and this escaping through the perforations A in the tip burns and emitsagood and steady illuminating-fiame.

which operates rod F and lever-F causin the cap or hood F to fall overon its hinge F and closely fit the tip A, and thus cut off the supply ofoxygen and smother or extinguish the flame. In using the burners shownin Figs. 1 and 2 it is necessary to out off the flow of oil to theburner by manipulating the tap or valve C? or other regulatingcontrivances.

It is to be understood that though I have shown what Iconsider to be thebest construc- 1 tions of this improved burner, yet I do not confinemyself to the precise details described and illustrated so long as thenature of this invention be retained.

In extinguishing the lamp the thumb-piece F is pushed to operate lever F7 Having now particula rlydescribed and explained the nature of myinvention and in what manner the same is to be performed, I declare thatWhat I claim is- 1. In a burner for oil-lamps, the combination with thevaporizing-cell B, and a filling B of fibrous or porous material placedin said cell, of the perforated refractory tip A having in its sides thegrooves A into which are sprung the upper edges of the vaporizing-celland provided on its under side with projections A that are extended intothe filling in the vaporizing-cell, substantially as described.

2. In a burner for oil-lamps, the combination of the vaporizing-cell Bhaving a filling B of fibrous or spongy material, the perfo-
